Application filed December 12, 192?. Serial No. 239,532.

The invention relates to devices for separatingjliquids'of diflerent specific gravity and for cleaningthe lighter liquid of comparatively heavy foreign matter held in suspension therein. Y The device is particularly advantageousfor separating water and any solid dirt from oil or gasoline. i

It is the object of the invention to provide an exceptionally simple and inexpensive, yet

an cfiicient and reliable device of the class set forth, and with this object in "view, the invention resides in the novel subject matter hereinafterdescribed and claimed, the de scription being accomplished by reference to the accompanying drawing.

Fig; 1 is a longitudinalsectionalview partly in elevation of a catch bowl constructed in .accordance with my invention. I

Fig.- 2 1s a vertical transverse sectional view on line2.2 of Fig. 1.

Fig. 3 is a top plan view of the partition.

' which extends horizontally across the bowl below the liquid inlet and outletand is provided with means for separatingthe lighter liquid from the heavier liquid, etc.

The drawing above brieflydes'cribed illushates the preferred form of construction, and

while this construction will be herein specifically described, it is to be understood that within the scope of the invention as claimed, variations may be made.

The numeral 4 denotes a bowler casing entirely open at its upper end and provided with a removable cover 5 and equipped at its partitioned by a lower end with a'suitable drain Valve or the like 6. The casing or bowl 4 is horizontally )late 7 into upper and lower chambers 89, the liquid inlet 10 and the liquid outlet 11 being in communication with said upper chamber, with their lower sides substantially flush-with the upper side of the plate 7. Preferably, the outlet 11 is somewhat higherthan the inlet 10 and the portion 12 of the plate 7 toward said outlet, is inclined to the latter, whereas the other end portion 13 of said plate is horizontal. End

portion 13 is formed with a plurality of transverse slots 14 and is provided with transverse flanges 15 which incline toward the inlet 10 from the edges of said slot-s remote from said inlet. The'end portion 12 of the plate 7 is formed with a plurality of transverse slots 16 and with transverse flanges 17. These flanges incline toward the outlet 11, from the edges of the slots 16, remote from one flange 17 for'each said outlet, the slots 14 and 16 and theflanges 15 and 17 extending continuously or uninterruptedly across the plate to near the op- .Owing to" the inclination of the end portion 12 of the partition p1ate7, the pressure will be greater toward the outlet'll' and hence the heavier liquid remains in the chamber -.'9 until the latter is-so full thatsaid liquid rises above the partition plate 7 The flanges 17 will catch any sluggish. or foreign matter that may be in the liquid flowing over the plate? and will upwardly direct the lighter liquid while the heavier foreign matter will drop over these flanges andth'rough the slots 16, into thev chamber 9. Any desired number of the flanges 15 and 17 may be provided. Usually, the're is one flang'e 15 for each inch of diameter of the inlet 10 and inch'of diameterof the outlet 11.-- I r In addition to the details above described, the longitudinal edge 1 portions of the plate 7 maybe formed with openings 18,'t.l1rough which any heavy liquid which may be sliding along the'edge portions of said plate, may descend into the chamber-9.

The plate 7 may be mounted in any desired manner within the bowl or casing 4. For illustrative purposes, I have shown-its. ends secured upon ledges 19 by means of screws 20, whilethe longitudinal edge por On account of the excellent results ob- ,preferably followed- However, within the may be made.

" I claim: 1

1. A liquid separator comprising acasing having 1n one end of its upper portion an tainable from the details disclosed, they are inlet opening and in the opposite end of said .upper portion an outlet opening, said outlet opening" being in aplane above the plane of said inlet opening, a partition plate ar-' ranged transversely within said casing and dividing the latter into upper and lower chambers, substantially-one half of said plate being on a level with the lower edge of said 11 inlet opening, the other half of the plate inlet and outlet portions of said plate, said slots extending from one longitudinal edge to the other longitudinal edge of the plate, ainl means on said partitions for effecting passage of heavy liquid and particles through said slots.

2. A liquid separator comprising a casing having in one end of its upper portion an inlet opening and in the opposite end of its upper portion an outlet. opening, said outlet opening being in a plane above the plane of the inlet opening, a partition plate arranged transversely -.within said casing and dividing the latter into upper and lower chambers, substantially one half of said plate being on a level with the lower edge of said inlet opening, the other half of the plate inclining upwardly to the lower edge of said outlet opening, a transverse slot in the inlet portion of said plate, said slot extending from one longitudinal edge to the other longitudinal edge of the plate, a similar transverse slot in the outlet portion of said plate, and extending from one longitudinal edge to the other longitudinal edge of the plate, additional openings along the longitudinal edges of the plate between said slots, liquid deflecting flanges on said plate, one of said flanges projecting from the edge of the transverse slot in the inlet portion of the plate re mote from the inlet end of the casing and inclining in the direction from which the liquid flows, the other liquid deflecting flange projecting from the edge of the transverse slot in the outlet portion of the plate remote from the outlet end of the casing and inclining in the direction of the flow of the liquid, and a valve in the lower portion of the casing.

3. A liquid separator comprising a casing entirely open at its top, a removable cover for said open top, said casing having in the opposite ends of itsupper portion inlet and outlet openings, said outlet opening being in a plane above the plane of the inlet opening, a transverse partition plate detachably secured in said casing and dividing the latter into upper and lower chambers, said plate being of considerably greater width than the diameter of said'inlet. and outlet openings but removable through said open top of the casing, substantially one halfof said plate being on a level with the lower edge of said inlet opening and the other half inclining upwardly to the lower edge of said outlet opening, said plate being formed with transverse heavy liquid discharging passages and means on said plate for effecting passage of heavy liquid and particles through said passage.

In testimony whereof I have hereunto affixed my signature.
